Differential Refractometric Analyzer

A differential refractometer measures the concentration or purity of a substance by comparing the difference in refractive index between the sample and a reference solution. It utilizes the change in the angle of refraction as light passes through two media to detect variations in solution composition. It is commonly used in quality control and component analysis in the chemical and food industries.
Selection
When selecting a differential refractometer, it is essential to consider a measurement range that covers the refractive index of the samples, sensitivity that matches the detection requirements, and temperature control stability suited to the operating environment. Attention should also be paid to the instrument's chemical compatibility with commonly used solvents, an interface that aligns with user habits, and maintenance costs that fit within the budget.
